EX8216 Ethernet Switch
Product Overview
Product Description
The EX8216 Ethernet Switch, a
The 16-slot Juniper Networks® EX8216 Ethernet Switch, part of the Juniper Networks
member of Juniper Networks EX
EX8200 line of Ethernet Switches, offers a high-density, high-performance platform
Series Ethernet Switches product
for aggregating access switches deployed in data center top-of-rack or end-of-row
family, delivers the performance,
applications, as well as for supporting Gigabit Ethernet and 10 Gigabit Ethernet server
scalability, and high availability
access in data center end-of-row deployments. The EX8216 delivers approximately
required for today’s high-density
1.9 billion packets per second (Bpps) of high-density, wire-speed 10-Gigabit Ethernet
data center, cloud computing, and
performance for the largest data center networks.
Internet exchange environments.
The EX8216 modular switch scales
beyond 12 terabits per second
(Tbps), delivering a robust solution
for today’s high-performance
networks while providing sufficient
capacity to support the most
demanding network environments
To maximize network investments, the EX8216 leverages the same EX8200 wire-speed
line cards and power supplies used by the eight-slot Juniper Networks EX8208 Ethernet
Switch, ensuring consistent performance across the entire product family. Working with
the EX8208, as well as Juniper Networks EX2200, EX3200, EX3300, EX4200, EX4500
and EX6200 lines of Ethernet switches, which all run the same Juniper Networks Junos®
operating system, the EX8216 helps reduce capital and operational expenses across the
data center infrastructure.

in the future.
The EX8216 modular switch includes an advanced set of hardware features enabled
by the Juniper-designed EX-PFE2 ASICs. Working with the carrier-class Junos OS, the
EX-PFE2 ASICs on each line card deliver the scalability needed to support highperformance data center networks.
The EX8216 switch can accommodate any combination of EX8200 line Ethernet line cards.

protocols such as 802.3ad, OSPF, Internet Group Management
Protocol (IGMP), Physical Interface Module (PIM), BGP and
others running on an EX8200 Virtual Chassis system behave in
exactly the same way as when running on a standalone chassis.
The EX8216 architecture was designed for very large data center
deployments, with no head-of-line blocking, a single-tier lowlatency switch fabric, efficient multicast replication handling,
and deep buffering to ensure performance at scale. The EX8216
chassis midplane distributes the control and management
signals over independent paths to the various system
components and distributes power throughout the system.
Data plane signals pass directly from the EX8200 line cards to

render the entire fabric inoperable following a failure. Virtual
Chassis technology also makes server virtualization at scale
feasible by providing simple L2 connectivity over a very large pool
of compute resources located anywhere within a data center.
Virtual Chassis technology can also be used to extend EX8200based VLANs between data centers by placing an equal number
of switches in both data centers, or by interconnecting two
separate Virtual Chassis configurations using a simple L2 trunk.
To maintain uninterrupted operation, the EX8216 switch’s two
fan trays cool the line cards, Routing Engine, and switch fabric
modules with redundant, variable speed fans. The EX8200 line’s
power supplies convert building power to the internal voltage
required by the system.
All EX8216 components are hot-swappable, and all central
functions are available in redundant configurations, providing high
operational availability by allowing continuous system operation

Architecture and Key Components
Juniper Networks EX8200 line of Ethernet switches, including
the EX8216 and EX8208, share a number of distinct architectural
elements. The Routing Engines employed by these switches
run Junos OS, which processes all Layer 2 and Layer 3 protocols
and manages individual chassis components, while the switch
fabrics provide the central crossbar matrix through which all
data traffic passes.
The EX8216 switch’s Routing Engine is based on the same fieldproven hardware architecture used by Juniper Networks routers,
bringing the same carrier-class performance and reliability to
the EX8216 that Juniper’s routers bring to the world’s largest
service provider networks. The Routing Engine’s central CPU
performs all system control functions and maintains hardware
forwarding table and routing protocol states for the EX8216
switch. Dedicated hardware on the Routing Engine module
supports chassis management functions such as environmental
monitoring, while communication between Routing Engine
modules and individual line cards takes place over a dedicated
internal Gigabit Ethernet out-of-band control interface.

The switch fabric for the EX8216, distributed across eight rearaccessible switch fabric modules, serves as the central nonblocking matrix through which all network data passes. All eight
SFMs in the EX8216 are always active, providing ample capacity
to deliver line-rate Layer 2 and Layer 3 switching on all ports for
packets of any size. If one switch fabric module were to fail, the
remaining modules gracefully load-balance the data traffic to
maintain line-rate performance on all 10-Gigabit ports without
dropping packets. The SFMs are hot-swappable and fieldreplaceable, enabling failed units to be easily replaced without
deliver up to 320 Gbps (full duplex) of packet data bandwidth
per line-card slot. The EX8216 backplane connector system is
designed to support switch fabric bandwidth of more than 12.4
Tbps—enabling the capacity of the EX8216 to potentially more
than double in the future.
The EX8216 chassis contains six power supply bays, providing
complete flexibility for both provisioning and redundancy. The

EX8216 also supports a 2,000 W power supply for high/low-line
operation at 2,000/1,200 W. A redundant-input 3,000 W DC
power supply is also available for central office deployments. The
EX8200 power supplies are more than 90 percent efficient at a
wide range of loads, minimizing building power requirements and
reducing overall power consumption. These power supplies are
interchangeable across the EX8200 line, simplifying maintenance
and sparing.
Although only two power supplies are required for basic
EX8216 configuration and power-up, the six power supply bays
provide the capacity required to power all possible line-card
configurations, and to support N+1 or N+N power redundancy
to protect against both component and line input failures. The
actual number of power supplies required depends on the
combination of line cards installed and the desired level of
redundancy (see table). For example, 9,000 W is required to
support a chassis fully populated with 128 line-rate 10-Gigabit
Ethernet ports.
